I have a 600E running -STABLE, and sound works with just these options:

device pcm
options PNPBIOS

and maybe some BIOS tweak that I've forgotten about. :-) this yields the
following line at boot:

pcm0: <CS423x-PCI> at port 0x530-0x53f,0x388-0x38b,0x220-0x233 irq 5 drq
1,0 on isa0


one thing to be aware of is that pcm and APM do not play nice together: if
you suspend the machine, sound will be broken until the next reboot. I
doubt it's biting you now, of course.
